REGULATOR Fon @Ass-sara l Specification of Letters Patent,

pulman ned February 5,1906. serial No. 299.554,

To all whom it may concern:

Be 4it known that l, CHARLES J. JOHNSON,- a citizen of the United States, residing at the city of St. Louis, lState of Missouri., have injet which is particularly useful on Bunsen I shows a vertical section of the entire device. y

burnersand where it. is necessary tov introduce a jet for' mixture with air which can be regulated as to size.

Various devicesihave heretofore been employed, but which either depend on artificial pressure or which cut the jet into numerous suhjets, all of which fail to accomplish 'the best results. My device furnishes a solid cylindrical stream of gas, the size of which may be regulated as desired and from which maximum results can be obtained.

Referring to the accompanying drawings, which form a part ofthe specliication, Figure Fig. II shows a detail View, part in vertical section, of the gas-tube. Fig.. lll shows an elevation ci the device, showing maximum capacity. Fig.- IV is similar to Fig. HI, but showing a minimumcapacity.

l is the tube through which gas is intro-4 duced.A 2 is the conical-shaped end thereof, where ignition takes place.

3 is the 'surrounding protection, furnished Wlitlperforations 4, through which air is supp 1e 5 is a plug screwed. into an elbow ol the tube l, which protects anopening through which a bar 6 is inserted and which may be raised or lowered by a set-screw or key 7 The upper end of this is flared and cut with slits 8. The flaring shape retreats at the end 9 and is capable of compression, so that when bar 6 is screwed upward the ianges close, as shownin Fig. 1V, yet which leave a central oriice exactly round, allowing the exit of a circular jet of gas. Even though compressed to the minimum of bar 6, furnished with slits,'allows gas to escape, as shown in Fig. Il; It may, however, be constructed so Ythat. rit will be entirely closed. The gas isdcontrolled by the usual stop-cock.4 (Not shown.) The retreating ends 9 of the regulator iitsnugly in the inside of the cone 2,- so that the jet, whether large, Fig. III, or small Fig. IV, is relatively 'always thesame and enters the ignition-chambers at the exact center. There is no danger of its becoming clogged, as the flaring construction with slits 8 always provides more space than the size of the jet.

What I claim as new, and by Letters Patent, is- K In a regulator for gas-j ets, the combination of a tube provided with a conical end, said end having a round opening; a regulator havdesire to secure ing a round orifice seating -within said end and provided with longitudinal openings, which openings are broader midway their length than at their ends; and a means of raising or lowering said regulator in reference to said tube; substantially as described.
